Magic Tricks

Topits, originally, are attached to (either temporarily or, better, permanently by sewing) to a dinner/suit jacket. I cannot say if there are designs for some other sort of outer wear. However (and someone will correct me if my answer if too limited) for a button down only, you would need something such as T.K.O.2
(search TKO and you'll find several versions, colors with and without downloaded instructions, etc.) You'll have to flatten a golf ball, not an eight ball.

Being a general term, let us know a few things. Are you looking to vanish only? Vanish and recover? Produce? When you perform do you always wear a jacket? Jacket and tie? Button down shirt? Swim trunks (I've got one, somewhere under this gut, for that)?

Usually button shirt...lol...I have got too so your suggestion may work good for me... Vanish, recover is most important
